Answer:

POLYADENYLATION  mechanism.

Explanation:

This is the mechanism of adding a poly(A)tail to a mRNA to protect  the RNA.This tail is made up of adenosine monophosphate(AMP) compound, and therefore consists of only this purine base stretch.(adenine is purines).

Polyadenylation participate in production of mature mRNA for the process of translation in the cystosol, therefore ensuring stability.

However this tail shortened with time, and in extreme shortness the mRNA is degraded by enzymes in the cells.

Conclusively, the protection provided by the poly(A) tail

and production of mature mRNA  ensured the stability of these molecules

How will the stomata look with high water pressure
dalvyx [7]
The stomata of leaves are surrounded by guard cells. The guard cells help the leaves to regulate the rate of transpiration of water from the leaves by opening and closing the stomata. When water enter the guard cells, they swell and bulge and this makes the stomata to open. So, with high water pressure, the guard cells will stimulate the stomata to open. The reverse will be the case if the water pressure is low.
